Fireman Tony with the Countryside Fire Department gave a presentation on fire safety to sixth-grade science classes at Middle School South. He spoke about the importance of changing batteries in fire detectors every six months, and installing a fire detector on every level of a home. He also spoke about sprinklers and how they release 15 gallons of water per minute when they are activated.  Using a mobile demonstration unit, he showed how quickly a fire can be stopped by a single sprinkler.
